FRAME FOR SUPPORTING COATED ARTICLES.

Specification of Letters Patent.

Patented May 23, '1911.

Application filed August 5, 1909. Serial No. 511,465.

a full, clear, and exact description thereof.

My invention relates to frames for supporting coated metal sheets or plates, and has special reference to such sheets or plates which are coated with enamel, lacquer or other like material in any suitable manner, or such as by the apparatus illustrated and described in an application filed by me of even date herewith, Serial No. 511,464, for machines for coating metal sheets.

The obj eet of my invention is to provide a cheap, simple and efficient holding or supporting frame for these coated metal sheets or plates, in which such sheets or plates can be supported thereon during handlin or while being carried after being coate for baking or drying the same, so as to prevent marring or injury to their coated surfaces, and thereby thus enable the sheets or plates to have a neat and perfect appearance to the eye when finished and ready for marketing.

My invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved supporting frame for coated metal sheets or plates, I will describe the same more fully, referring to the accompanying drawing, in which Figure l is an inverted plan view of my improved frame for supporting coated sheets or plates. Fig. 1 is an end view of a movable truck for carrying the coated sheets or plates having my improved supporting frame employed therewith. Fig. 2 is an enlarged top plan view of the frame bars. Fig. 3 is a sectional view of the bar, showing some of the parts in full lines and in their lowered or inoperative positions. Fig. 4 is alongitudinal section of the bar similar to Fig. 3, showing some of the parts in full lines and in their operative positions. Fig. 5 is an enlarged cross-section of the bar on the line 55 Fig. 4, looking in the direction of the arrow.

Like symbols of reference herein indicate like parts in each of the figures of the drawmg.

As illustrated in the drawing, 1 represents the truck for holding and carrying the metal sheets 01' plates after being coated in any suitable manner, and it is mounted upon wheels 2 for moving the same.

The supporting frame is shown at 3, and,

it is formed of thin sheet metal having the cross-bars 4 of channel-shape and the supporting bars 4 mounted thereon. The bars 4 are each provided with a main trough member 5 which is formed in channel shape, and within and extending across said member are a series of cross-plates 8, of channel shape. These plates 8 act as braces by being attached in any suitable manner to the sides 6 of the trough through their angular ends 9, and their body portions 10 are placed adjacent to the bottom 7 of said trough, so as to form guides between said bottom and said portions for the sliding plate member 11. Secured in any suitable manner to the bottom 7 of the trough 5 on the bars 4 are a series of spring members 12 which have spring portions 13 thereon and provided with sharpened and pointed ends 14 projecting upwardly at about right angles to the same and in substantially a vertical line therefrom. These spring members 12 are adapted to engage with the inclined portion 15 on the raised portions or projections 16 through their spring portions 13, which projections extend up in a vertical lme from the sliding member 11, and lips 17 on said member are adapted to extend over said spring portions to hold the members 12 in their lowered positions. A handle or finger portion 18 projects downward from the end of the sliding member 11 for moving the same within the trough 5.

When the supporting frames 3 are to be used, the operator through the handles 18 pushes in the sliding members 11 on the bars 4, which will allow the inclined faces 15 of the projections 16 on the members 11 to come in contact with and under the spring portions 13 on the members 12 and thereby raise said members 12 and with them the ends 14 thereof. WVith the ends 14 in this raised position the coated sheets or plates at are placed upon the frame 3, so thatsuch ends will engage with and support such sheets or plates thereby, and preferably two of such bars are used on a frame for supporting a single sheet or plate and at each end of the same. When each of the frames 3 are supporting each of the coated sheets or plates a upon the truck 1, the lower frame will rest upon the bed 1 of the truck 1 by its crossbars 4, and the other frames will rest upon one another above the same, with the cross bars 4 resting upon the bars 4, so that the sheets or plates will be held from contact with the frames as they are held on the truck, and when a sufficient number of coated sheets or plates a are thus placed on the car riage 1 by'the frame 3, the truck is moved to the drying place or baking oven to dry or bake such sheets or plates as desired and in the usual manner. After the sheets or plates a are dried or baked, they can be removed from the truck 1 by lifting the same from the bars 4 on the frames 3 and then lifting the frames from the carriage or by lifting the frames and plates together and from the carriage, and then removing the plates from the frames, as desired.

When the supporting frames 3 are not in use in connection with the sheets or plates at and in order to inclose the ends 14 on the spring members 12 within the troughs 5 of the bars, the operator pulls out the sliding members 11 through the handles 18, which will act to withdraw the inclined portions 15 on the projections 16 from under the spring portions 13 on said members 12, and thereby lower said members and their ends 14 within said troughs, as shown in Fig. 3.

The bars 4 can be disconnected from each other as shownin Figs. 4 and 5 and used separately, while various other modifications and changes in the design, construction and operation of my improved supporting frame for coated metal sheets or plates may be resorted to, without departing from the spirit of theinvention or sacrificing any of its advantages.

It will thus be seen that my improved supporting frame for coated metal sheets or plates will enable the handling and holding of the coated sheets or plates without scratching, defacing or injuring the coated surfaces of such sheets or plates to any ex tent whatever, so that such plates when ready for the market will be free from any imperfections or objections through unsightly surfaces thereon and will therefore present a finished and perfect article for commercial use. The device being capable ofhaving its supporting means inclosed or brought within the same will prevent such means from being in the way when not in use, and so permit the device to assume a compact form for handling, shipping or storage.

What I claim as my invention and desire to secure by Letters Patent, is-
